I just realized this advantage of a dry rope a few days ago, so strange to see it 'confirmed'. I bought my first ever non-dry rope last year, and despite very, very little use, it is now significantly dirtier than any previous rope I have owned.

I own 11 ropes right now, 7 are dry ropes, the others are not. All of them are equally dirty in reference to the type of use and amount of use they have been seeing. The dry coating put onto ropes is mostly a gimmick. It works great when the rope is brand new, but with minimal use even the best dry coatings will wear off very quickly.
